Title: Phase difference mask
Inventor: ABE KAZUTOSHI
IPC: G03F1/30
Filed: 1989-10-30
Abstract: PURPOSE:To inspect the position and the defect of a phase shifter layer by comprising the mask of an organic film containing dye whose transmission factor is set at a high level with first wavelength and a low level with second wavelength and with film thickness capable of discriminating light intensity at the second wavelength for the light intensity of a projection image by the first wavelength. CONSTITUTION:The phase shifter layer 13 consisting of the organic film to supply a phase difference of 180 deg. to the amplitude of light L is formed at a part of the surfaces of a glass layer 11 and a light shielding layer 12. The dye to inspect the position and the defect, etc., is contained in the phase shifter layer 13, and the phase shifter layer 13 is comprised of the organic film having the first wavelength lambda1 with high level of light transmission factor and the second wavelength lambda2 with low level of light transmission factor. Therefore, the phase difference shifter layer 13 can be inspected by using the second wavelength lambda2 with low level of light transmission factor. In such a way, it is possible to easily inspect the position and the defect, etc., of the phase shifter layer without changing a transmission light quantity.

IPC: C09D5/23
Filed: 1990-10-20
Abstract: PURPOSE:To obtain a magnetic powder which is excellent in corrosion-resistant property and whose saturation magnetization is high as a metallic magnetic powder and to obtain its proper manufacturing method by a method wherein metallic powder obtained by reducing an iron oxide-based powder in a vapor phase is hydrolyzed and treated in an organic solvent containing a specific component and it is heated and treated in the current of dilute oxygen. CONSTITUTION:This magnetic powder is formed in such a way that a ferromagnetic ferrite layer at 5 to 70vol.% with reference to a metal core composed mainly of iron is provided on the surface of the metal core. In the manufacturing method of the powder, an iron oxide-based powder as a raw-material is first reduced in a vapor phase, a metal powder composed mainly of iron is formed, and the metal powder is dispersed and hydrolyzed in an organic solvent with which an alkoxide containing a ferrite formation component has been mixed. Thereby, the hydrolyzed product of the alkoxide is applied to the surface of powdery particles; then, the particles are heated and treated in an inert gas containing a very small amount of oxygen gas; the magnetic powder provided with the ferromagnetic ferrite layer on the surface of the metal powder is obtained. Since, at the magnetic powder, a corrosion-resistant property is good, its saturation magnetization is high and it is provided with a very excellent property as a recording element for high-density recording use.

Title: Input circuit for semiconductor integrated circuit
Inventor: YOSHIMASU TOSHIHIKO
IPC: H03H11/28
Filed: 1990-10-19
Abstract: PURPOSE:To widen a frequency band, and besides, to miniaturize the integrated circuit by providing a bias circuit at the input side of a filed effect transistor with another gate-earthed field effect transistor. CONSTITUTION:The source 2 of a field effect transistor 1 (first FET) is connected to the drain 31 of another field effect transistor (second FET) 30 to be used as the bias circuit of the first FET 1, and both the source 33 and the gate 32 of the second FET 30 are earthed. Accordingly, a DC current to flow between the drain and the source of the first FET 1 flows between the drain and the source of the second FET 30, and a loop of the current is formed. Since resistance between the drain and the source of the second FET 30 is large, the damping of a microwave is small, and in addition, a DC voltage drop between the drain and the source can be suppressed to about 1 to 2 V. Thus, transmission loss in the bias circuit can be made nearly zero, and in addition, DC supply voltage can be made low, and besides, the wide frequency band of an input circuit can be realized, and the miniaturization of the integrated circuit can be attained.

The optical fiber 20 is exposed repeatedly to the arc at successive positions along the length. This is carried out by turning off the current source, advancing the optical fiber in the holder, and igniting the arc again. When the optical fiber 20 is exposed to the electric arc, variation in refractive index is generated.

Title: Method for instructing parking position
Inventor: NISHI KENICHI
IPC: G08G1/14
Filed: 1987-11-10
Abstract: PURPOSE:To accurately control a parking zone by informing the section number of an empty parking section to a driver through sound when a parking ratio excluding sections which can not be temporarily used has exceeded a previously set value. CONSTITUTION:A parking state is always monitored by a signal processing means 7 on the basis of signals from respective sensors S1-Sn and parking sections P1-P2 which can not be temporarily used and inputted from a keyboard 10. Since plane observation in a parking zone may be fairly deteriorated when a parking ratio shown by a circular graph G for convenience excluding the sections which can not be temporarily used has exceeded the previously set value, e.g. 75% shown by oblique lines, an empty section is instructed to a driver to be entered. When an empty section excluding sections which can not be temporarily used exists, a signal for converting a section number into sound is outputted from a sound synthesis and output device 6 and applied to a speaker 4 through an AMP 5. Then, the speaker 4 outputs sound so that the driver can confirm the sound. Thus, the parking zone can be accurately controlled.

Abstract: PROBLEM TO BE SOLVED: To obtain a moving position measuring instrument which only has a signal communicating function as a mobile station and can be carried conveniently by making the instrument transmit and receive signals to and from a plurality of fixed stations at known locations for finding the relative distance of the instrument. SOLUTION: A moving position measuring instrument is constituted of a mobile station M which is carried by a walker and has a signal communicating function, fixed stations A, B, and C the positions of which on a latitude longitude coordinate system are known, and a host station H. When the mobile station M transmits a trigger radio wave, the radio wave receiving time of the fixed stations A, B, and C are informed to the host station H.

Then the relative position is converted into an absolute position on the latitude-longitude coordinates and the data of the absolute position are transmitted to the mobile station M from the host station H.
